An example of some awful PHP code I once reviewed. Saved for posterity.

dan.php

<?php

function blogPreviews($numberOfPosts)
{
    $blogPreviews = [];

    $args = array(
        'numberposts' => $numberOfPosts
    );

    $blogPostsData = get_posts($args);

    $themeColors = array(
        '1' => 'coral',
        '2' => 'blue',
        '3' => 'turquoise',
        '4' => 'blue',
        '5' => 'purple',
        '6' => 'maroon',
        '7' => 'green'
    );

    $styles = array(
        '1' => 'wide',
        '2' => 'full',
        '3' => 'short',
        '4' => 'full',
        '5' => 'short',
        '6' => 'full',
        '7' => 'wide'
    );


    if ($blogPostsData) {

        $count = 0;

        foreach ($blogPostsData as $currentPost) {

            $count++;

            if ($count == '1' || $count == '7') {
                $class = "medium-first";
            } else if ($count == '2' || $count == '5') {

            $imageAttr = array(

                'text'          => get_the_excerpt($currentPost->ID),
                'id'            => $currentPost->ID
            );

            $blogPreviews[] = $blogPreview;
